Setup and Connection
Before using the Verbatim Dual USB Flash Drive, ensure your mobile device supports USB On-The-Go (OTG) functionality. Most modern Android smartphones and tablets support OTG, but it is advisable to check your device's specifications.
Connecting to a Mobile Device (OTG)
- Locate the Micro-USB port on your smartphone or tablet.
- Carefully insert the Micro-USB connector of the flash drive into your device's Micro-USB port. Ensure it is inserted correctly to avoid damage.
- Your device should automatically detect the flash drive. A notification may appear, or you may need to navigate to your device's file manager application to access the drive.
Connecting to a Computer (PC/Mac)
- Locate an available USB-A port on your computer.
- Insert the standard USB-A connector of the flash drive into the computer's USB-A port.
- The computer should detect the drive as a removable storage device. It will appear in 'My Computer' (Windows) or on the desktop/Finder (Mac).

Operating Instructions
Transferring Files
Once the flash drive is connected and recognized by your device or computer, you can transfer files using standard drag-and-drop operations or copy/paste functions.
- From Mobile Device: Open your device's file manager. Navigate to the files you wish to transfer. Select them and choose to 'Copy' or 'Move' them to the flash drive's directory.
- From Computer: Open 'My Computer' (Windows) or Finder (Mac). Locate the files on your computer. Drag and drop them into the flash drive's folder, or right-click and choose 'Send To' (Windows) / 'Copy' then 'Paste' (Mac/Windows).
Accessing Content Directly
You can play media files (photos, videos, music) or open documents stored on the flash drive directly from your OTG-compatible mobile device without transferring them to the device's internal storage. Use your device's file manager or a compatible media player application to browse and open files on the connected flash drive.

Maintenance
To ensure the longevity and optimal performance of your Verbatim Dual USB Flash Drive, follow these maintenance guidelines:
- Physical Care: Avoid dropping the drive or subjecting it to strong impacts. Keep it away from liquids, dust, and extreme temperatures.
- Connector Protection: The Micro-USB connector, especially, can be delicate. Handle it with care during insertion and removal to prevent bending or damage.
- Safe Removal: Always safely eject the flash drive from your computer before physically removing it. On Windows, use the 'Safely Remove Hardware' icon in the system tray. On Mac, drag the drive icon to the Trash or use the Eject button in Finder. For mobile devices, ensure no file transfers are active before unplugging.
- Storage: When not in use, store the flash drive in a clean, dry place, ideally with the protective cap on the Micro-USB connector.
Troubleshooting
If you encounter issues with your Verbatim Dual USB Flash Drive, consider the following troubleshooting steps:
- Drive Not Recognized:
- Check Compatibility: Ensure your mobile device is USB OTG compatible.
- Re-insert: Disconnect and re-connect the drive firmly to the port.
- Try Different Port/Device: Test the drive on a different USB port on your computer or another OTG-compatible mobile device to rule out a port issue.
- Restart Device: Sometimes, restarting your computer or mobile device can resolve detection issues.
- Slow Transfer Speeds:
- USB 2.0 Standard: This drive operates on USB 2.0, which has slower speeds compared to USB 3.0 or higher. Expect transfer rates typical for USB 2.0 devices.
- File Size: Transferring many small files can be slower than transferring a single large file of the same total size.
- Micro-USB Port Damage: Handle the Micro-USB connector with extreme care. Repeated forceful or incorrect insertion can damage the port on the flash drive or your mobile device. If the port is physically damaged, the drive may no longer function with mobile devices.
- Data Corruption: Always safely eject the drive. Unplugging it during a transfer or without proper ejection can lead to data corruption. If data appears corrupted, you may need to reformat the drive (Warning: This will erase all data).
